    CROSS REFERENCE TO RELATED APPLICATIONS The present application claims priority from U.S. Provisional Patent Application 62/519,385, filed July 14, 2017, the entire contents of which are incorporated by reference into the present application.
    TECHNICAL FIELD The technical field relates generally to seat assemblies, and more particularly to such seat assemblies, for example for an aircraft and the like, which have an armrest with an armrest cover and a joint arrangement for opening and closing the armrest cover.
    BACKGROUND Today's seat assemblies, for example, for the commercial and / or military transportation industry (e.g., aircraft, automobiles, and the like) often have an armrest that has a single pivot joint for opening and closing an armrest cover. Since the seats can be stowed outboard immediately adjacent to a side wall protrusion that has, for example, a cup holder rail, a storage area and / or the like, the space for opening and closing the armrest cover can be very limited. This limited space can make it difficult and / or prevent the use of a functional armrest cover that can be opened and closed, for example, on the outboard side of the seat adjacent to the cabin wall, since the cover and the side wall protrusion can interfere with each other when the seats are outboard are stowed. Furthermore, today's armrest covers (for example arranged on the inboard and / or outboard side of a seat assembly) can inadvertently open or close, for example when a passenger rises from the seat, and presses downwards and outwards on the armrest cover, which results in the armrest cover The armrest cover opens and turns away from the passenger.
    Therefore, it is desirable to provide seat assemblies that have an armrest with an armrest cover that address one or more of the foregoing issues. Furthermore, other desirable features and characteristics of the various embodiments described herein will become apparent from the following detailed description and the appended claims, taken in conjunction with the accompanying drawings and this background.
    SUMMARY Seat assemblies are provided that have an armrest. In an exemplary embodiment, a seat assembly includes a seat base portion and a seat back portion that at least partially include a seat frame that supports the seat back portion that extends substantially upright from the seat base portion. An armrest is arranged near the seat base section and in front of the backrest section. The armrest has a fixed armrest section which is coupled to the seat frame. An armrest cover is configured to move relative to the fixed armrest section between a closed position, overlaying an upper section of the fixed armrest section, and an open position, which allows access to the upper section of the fixed armrest section. A hinge arrangement pivotally couples the armrest cover to the fixed armrest section. The hinge assembly includes a damper and damper gear that meshes with the damper to dampen movement of the armrest cover between the closed and open positions.

    DETAILED DESCRIPTION The following detailed description is intended to be exemplary only and is not intended to limit the various embodiments or their application and uses. Furthermore, it is not intended to be bound by any theory presented in the foregoing background or the detailed description that follows.
    Various embodiments considered here relate to seat assemblies which have an armrest with an armrest cover and a joint arrangement for opening and closing the armrest cover. In a first exemplary embodiment, a seat assembly has a joint arrangement for an armrest cover, which has two guide bearings in a guideway. The two guide bearings are coupled via a linkage to a damper gear which meshes with a damper (e.g. rotary damper) mounted on the fixed portion of the armrest of the seat assembly to control and limit the opening and / or closing of the armrest cover. The two guide bearings in the guideway control and limit the area of opening the armrest cover so that the armrest cover does not interfere with a side wall protrusion, for example, when the seat is stowed outboard. Furthermore, the damper transmission and the rotary damper dampen the movement (e.g. damping or controlling the speed and force) of the armrest cover during opening and closing to help prevent the armrest cover from accidentally opening and closing, for example when when Passenger leaves the seat, or for any other reason.
    In a second exemplary embodiment, a seat assembly has a joint arrangement for the armrest, which has two connecting links, for example an upper connecting link and a lower connecting link. The two connecting links control the opening and / or closing of the armrest cover. The upper link supports the limitation of the opening area of the armrest cover so that the armrest cover does not interfere with the side wall protrusion, for example, when the seat is stowed outboard. Furthermore, the lower link is coupled to a damper gear which meshes with a damper (e.g., a rotary damper) mounted on the armrest portion of the seat structure to dampen movement of the armrest cover (e.g., dampen or control speed and force) during opening and closing to help prevent the armrest cover from accidentally opening and closing, for example when a passenger leaves the seat or for other reasons.
    1 shows a perspective front view of a seat assembly 10 according to an exemplary embodiment. As shown, the seat assembly 10 is disposed near an outboard side wall 12 and also adjacent to a protrusion 14 in a cabin 16 (e.g., the cabin of an aircraft). The seat assembly
    CH 713 878 A2 has a seat section 18, a backrest section 20, and two armrests 22. The armrests 22 are arranged in the vicinity of the seat base section 18 and in front of the seat back section 20, which correspond to the outboard side (indicated by arrow 24) and the Inboard side (indicated by arrow 26) facing the cabin 16.
    As shown, the seat back portion 20 extends substantially upright from the seat base portion 18. In one example, the seat back section 20 is fixedly coupled to the seat base section 18 such that the seat back section 20 is continuously adjusted to a substantially upright configuration. In another example, the seat assembly 10 is an adjustable seat assembly in which the seat back portion 20 is pivotally coupled to the seat base portion 18 for movement between a substantially upright position and, for example, a substantially reclined and / or tilted position (e.g., tilted forward) ).
    The seat assembly 10 includes a seat frame 28 that forms at least a portion of the seat base portion 18 and the seat back portion 20, and supports the seat back portion 20 that extends substantially upright from the seat base portion 18, as mentioned above. Seat frame 28 is made of a relatively rigid support material, such as metal, such as aluminum and the like, composite, or any other frame structure material or materials known to those skilled in the art.
    Each armrest 22 has a fixed armrest portion 20 which is (directly or indirectly) coupled to the seat frame 28 which holds the armrest 22, and an associated armrest cover, supports and / or the like, which are attached to the seat frame 28 , As will be explained in more detail below, an armrest cover 34 is pivotably provided on each of the fixed armrest sections 30 via a joint arrangement 32. The armrest cover 34 is configured to move relative to the fixed armrest section 30, between a closed position 40, in which it lies over an upper section 42 of the fixed armrest section 30, and an open position 44 (see FIG. 7) allows access to the upper portion 42 of the fixed armrest portion 30.
    2-13 contain different views of the armrest 22 with the armrest cover 34 and the joint arrangement 32 according to a first exemplary embodiment. 2-7 are sectional views of a first end (e.g., front end 36 or rear end 3.8) of the armrest cover 34 and hinge assembly 32 during various stages of opening and / or closing (movement between the closed position 40 and the open position Position 44) of the armrest cover 34, FIGS. 8-10 are side perspective views of the armrest cover 34 and the hinge assembly 32 during various stages of opening and / or closing the armrest cover 34, and FIGS. 11-13 are sectional views of a second end (e.g. the other, i.e. the rear end 38 or the front end 36) of the armrest cover 34 and the hinge arrangement 32 during various stages of opening and / or closing the armrest cover 32. As mentioned, the first end of the armrest cover 34 can be a front armrest cover end 36 , or alternatively a rear armrest cover end 38, and is the second end of the Armrest cover 34 has one end of the armrest cover 34 opposite the first end (see FIG. 1).
    2-10, as explained above, each armrest 22 has the fixed armrest portion 30, and the armrest cover 34 which is pivotally coupled to the fixed armrest portion 30 by the hinge assembly 32. As shown, the hinge arrangement 32 has two guide bearings 46 which are arranged in a guide track 48 (for example a recess or depression) which has, for example, a curved shape. A shaft 50 (for example, a pin or the like) is arranged between each of the guide bearings 46 and is attached to the armrest cover 34. The guideway 48 is provided in the fixed armrest section 30. A curved slot 52 is provided in the guideway 48 and correspondingly in the fixed armrest section 30. The shafts 50 extend through the slot 52 so that the guide bearings 46 can move within the guideway 48 when the armrest cover 34 is moved. In one example, the guide bearings 46 are free to rotate around the shafts 50.
    A coupler link 54 has two holes 56 which receive portions of the shafts 50 opposite the ends attached to the fixed armrest portion 30. In the present example, the coupler connector 54 is shown to have a substantially triangular shape. A damper connector 58 is rotatably coupled to the coupler connector 54, which is shown in this example in such a way that it essentially has the shape of an “L”. The damper link 58 is rotatably coupled to a damper gear 60 via a shaft or pin 52 in a lower portion of the damper gear 60. The damper gear 60 has two pins or shafts 62 with bearings 64 which are correspondingly (for example rotatably coupled) coupled to the pins or shafts 62. The two bearings 64 run in a vertical guideway 66 (for example a slot or the like) which is formed in the fixed armrest section 30. Here, the coupler link 54 and the damper link 58 form a linkage which couples the guide bearings 46 to the damper gear 60 so that the damper gear 60 is moved during the movement of the armrest cover 34. The damper gear 60 has teeth that mesh with a tooth of a damper 70 (e.g., a rotating damper) attached to the fixed armrest portion 30. Here, and as will be explained in more detail below, the coupler link 54 and the damper link 58 form at least part of a linkage which couples the guide bearings 46 in the guideway 48 to the damper gear 60 in order to move the damper gear 60 during the movement of the armrest cover 34.
    CH 713 878 A2 During movement of the armrest cover 34, for example from the closed position 40 shown in FIG. 2 to a fully open position 44 shown in FIGS. 7 and 10 (note that FIGS. 6 and 8-9 intermediate stages of opening and / or closing the armrest cover) force is transmitted from, for example, a seat occupant's hand to an upper corner (e.g. the left corner in this example) of the armrest cover 34 in a direction to open the cover (indicated by arrow 68). When the armrest cover 34 moves in the direction 68 of the cover opening, the two shafts 50 which are attached to the armrest cover 34 move together with the armrest cover 34, while the two guide bearings 46 run on the shafts 50 in the guideway 48 which is provided in the fixed armrest section 30. The coupler link 54, which is also coupled to the two shafts 50, moves accordingly with the armrest cover 34, whereby movement and / or force is transmitted to the shaft 72, which is rotatably coupled to the lower section of the damper transmission 60. Here, the damper gear 60 is pulled up or moved. The bearings 64, which are coupled to the damper gear 60 and run in the vertical track or slot 66 provided in the fixed armrest portion 30, ensure that the damper gear 60 is substantially vertical or rectilinear moved upward so that the teeth of the damper gear 60 can mesh with the teeth of the damper 70. The damper 70 is designed to control the speed and / or force for opening and closing the armrest cover 34. The guide track 48, in which the guide bearings 46 move, controls and / or limits the area of the opening of the armrest cover 34, so that the armrest cover 34 does not interfere with the side wall projection 14, for example, when the seat assembly 10 is stowed outboard. Furthermore, damper gear 60 and damper 70 dampen the movement of armrest cover 34 (e.g., damping or controlling speed and force) during opening and closing to help prevent armrest cover 34 from accidentally opening or closing, for example, then if a passenger leaves the seat, or for any other reason. In this example, the hinge assembly 32 as described above has a damper function.
    11-13, the second end or the other end (for example, 36 or 38) of the armrest cover 34 may have a joint arrangement 132, as explained above in connection with FIGS. 2-10, but without the damping function , In this example, and illustrated accordingly, the hinge assembly 132 includes the track 48, guide bearings 46, and shafts 50 as previously discussed, but without the damping function provided by coupler link 54, damper link 58, damper gear 60, and the damper 70 and associated bearings 64, pins and / or shafts 72 is provided.
    14-27 show different views of an armrest 22 with an armrest cover 34 and a joint arrangement 32 according to a second exemplary embodiment. 14-20 are sectional views of a first end of armrest cover 34 and hinge assembly 32 during various stages of opening and / or closing armrest cover 34. FIGS. 21-24 are side perspective views of armrest cover 34 and hinge assembly 32 during various stages opening and / or closing the armrest cover 34. FIGS. 25-27 are sectional views of a second end of the armrest cover 34 and the hinge assembly 32 during various stages of opening and / or closing the armrest cover 34. The first end of the armrest cover 34 may be a front end Armrest cover end 36, or alternatively a rear armrest cover end 38, and the second end of the armrest cover is an end of the armrest cover 34 opposite the first end (see FIG. 1).
    Referring now to Figs. 14-24. As shown, the armrest 22 has a fixed armrest portion 30 and the armrest cover 34 which is pivotally coupled to the fixed armrest portion 30 through the hinge assembly 32. As shown, the hinge assembly 32 has two links 74 and 76, e.g. an upper link 74 and a lower link 76. The upper link 74 is rotatably coupled to the armrest cover 34 (e.g. via a pin 78 or the like), with an axis of rotation ( the center of the pin 78) near the left end portion of the upper link 74. The right end portion of the upper link 74 has a bearing 80 (e.g. a head of a fitting screw) which is attached to a shaft 82 (e.g. the shaft portion of a Fit screw) which is attached to the fixed armrest portion 30. The upper link 74 is disposed in a guideway 84 (e.g., a recess or depression) that has, for example, side walls and, as shown, has a substantially pie-shaped configuration. In the fully closed position 40, as shown in FIG. 14, the top edge 86 of the top link 74 abuts against the top side wall of the pie-shaped track 84.
    The lower link 76 has a left end portion 88 and a right end portion 90. The right end portion 90 of the lower link 76 is rotatably coupled to the armrest cover 34. The left end portion 88 of the lower link 76 is rotatably coupled to the fixed armrest portion 30 and has a shaft 92 which is coupled to the lower link 76 and a bearing 94 which extends around the shaft 92. The shaft 92 is fixedly coupled to a damper gear 96. The damper gear 96 has teeth that mesh with the teeth of a damper 98 (for example, a rotary damper).
    During the movement of the armrest cover 34, for example from a closed position 40 as shown in Fig. 14, to a fully open position 44 as shown in Figs. 20 and 24 (note that the
    CH 713 878 A2
    15-19 and 21-23 intermediate stages of opening and / or closing the armrest cover 34), force is transmitted from, for example, the hand of a seat occupant to an upper corner (for example in the present example to the left corner) of the armrest cover 34 in one Direction 68 in which the lid opens. As the armrest cover 34 moves in the direction 68 to open the cover, the upper link 74 rotates about the axis of rotation such that the upper edge 86 of the upper link 74 moves away from the upper side wall of the track 84, while the lower edge 100 of the upper connecting member 74 approaches the lower side wall 102 of the guideway 84. When the lower edge 100 of the upper link 74 projects downward or contacts the lower side wall 102 of the track 84, the armrest cover 34 is in the fully open position 44, thereby controlling and / or limiting the opening area of the armrest cover 34, so that the Armrest cover 34 does not interfere with, for example, a side wall projection 14 when the seat assembly 10 is stowed outboard.
    Furthermore, the right end portion 90 of the lower link 76 moves together with the armrest cover 34, while the left end portion 88 of the lower link 76, which is rotatably coupled to the fixed armrest portion 30, rotates about an axis of rotation so that the shaft 92 correspondingly, the damper gear 76 rotates, which has teeth that mesh with the teeth of the damper 98. The damper 98 is attached to the fixed armrest portion 30 and is configured to provide a damper function. The damper function provided as described above dampens movement (e.g., dampens or controls speed and force) of the armrest cover 34 during opening and / or closing to help prevent the armrest cover 34 from being accidentally opened or closed, for example when a passenger leaves the seat, or for any other reason.
    As shown in FIGS. 25-27, the second end or other end (e.g. 36 or 38) of the armrest cover 34 may have a hinge assembly 132, for example as described above in relation to FIGS. 14-24, but without the damper function. In this example, and as shown, the hinge assembly 132 has two links 74 and 76, the track 84, bearings 80 and 94, and shafts 82 and 92 as discussed above, but without the damper function provided by damper gear 96 and the Damper 98 and associated bearings, pins and / or shafts is provided.
